§ 842. Computation of county equalization rates. The commissioner
shall compute county equalization rates for each county to which this
title is applicable by furnishing the final state equalization rates
which are established pursuant to article twelve of this chapter for
each city and town in the county for the final assessment roll to be
completed and filed during the current year or, if such rates are not
then available for each city and town in the county, by adjusting the
final state equalization rate established pursuant to article twelve of
this chapter for each city and town in the county for the final
assessment roll required to be completed and filed during the prior
calendar year by the appropriate "change in level of assessment", if
any, as that term is defined in section twelve hundred twenty of this
chapter. On or before the fifteenth day of November, or such other date
as may be prescribed by law for the determination of county equalization
rates, the commissioner shall certify the county equalization rates to
the clerk of the legislative body of each county to which this title is
applicable. Within five days of the receipt of such rates, the clerk of
the legislative body shall provide to each city and town a written
notice of the county equalization rates computed by the commissioner.
